silicon has fix oxidation state and tin has not yet so it show +4

Answer: This happens due to inert pair effect.
Explanation:
Inert pair effect is defined as the tendency of the two paired up electrons in the outermost s-orbital to remain unshared in bonding.
Tin and silicon belongs to the same group that is Group 14. The common oxidation state of this group is +4.
Silicon belongs to the period 3 and Tin belongs to Period 5. Therefore, inert pair is more prominent in Tin than in silicon. So, the two s-electrons in Tin remain unbonded and the oxidation state of +2 also appears.
Hence, tin shows an oxidation state of +2 and +4 but silicon only shows an oxidation state of +4.
